Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a coalescing dehydrator. Background Technology

[0002] Excessive water content in a water-hydrocarbon mixture can affect the normal operation of subsequent equipment. Therefore, it is necessary to remove the water from the mixture. This requires separation of the water-hydrocarbon mixture, followed by separate discharge of water and hydrocarbons. Water-hydrocarbon mixtures with high water content require treatment. However, due to poor sealing of the equipment, incomplete separation can easily occur during the separation of water-hydrocarbon mixtures.

[0003] Document CN 211500848 U discloses a three-stage fuel filter assembly and its fuel filter. The three-stage fuel filter assembly includes an outer core assembly, an inner core assembly, and a hydrophobic mesh assembly. The outer core assembly has an inner cavity, and the inner core assembly and hydrophobic mesh assembly are disposed within the inner cavity. The outer core assembly and the inner core assembly are not connected. The inlet of the hydrophobic mesh assembly is connected to the outlet of the outer core assembly, and the outlet of the hydrophobic mesh assembly is connected to the inlet of the inner core assembly. When the filter assembly filters, the fuel passes through the outer core assembly, the hydrophobic mesh assembly, and the inner core assembly sequentially, achieving three-stage filtration. This filtration structure has poor sealing after material enters, making it prone to leakage and incomplete filtration.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses a coalescing dehydrator. By engaging the inlet sealing end with the coalescing filter element, when a water-hydrocarbon mixture enters the upper part of the upper baffle inside the cylinder from the feed pipe, the sealing structure effectively prevents the water-hydrocarbon mixture from entering the coalescing chamber, allowing it to enter only from the inlet end of the coalescing filter element, thus ensuring thorough filtration of the water-hydrocarbon mixture.

[0006] The technical solution of this utility model is as follows: a coalescing dehydrator, including a filter element and a partition plate located inside the cylinder.

The top of the coalescing filter element is connected to the upper partition through a sealing structure.

[0009] By adopting the above technical solution, the water-hydrocarbon mixture in the upper part of the upper baffle first passes through the coalescing filter element, and then through the separation filter element, separating the water to the outer surface of the filter element, while the hydrocarbons drip down through the oil outlet pipe.

[0010] Preferably, the sealing structure includes a sealing cover plate and an inlet sealing end, the inlet sealing end being sleeved on the top of the coalescing filter element, and the inlet sealing end including an inlet end and a sealing end.

[0011] By adopting the above technical solution, the sealing structure allows the water-hydrocarbon mixture to be stored above the upper partition, filtered by the coalescing filter element, and then moved downwards, preventing the water-hydrocarbon mixture from directly entering the coalescing chamber.

[0012] Preferably, the inlet end extends through the top of the coalescing filter element, and the sealing end is integrally formed around the inlet end. The bottom of the sealing end is in the shape of an inverted U-shape with the opening facing downwards, and the sealing end fits perfectly into the top of both sides of the coalescing filter element.

[0013] By adopting the above technical solution, a mixture enters the coalescing filter element from the inlet end, and a sealing effect is achieved between the sealing end and the coalescing filter element.

[0014] Preferably, the lower bottom side of the sealing end abuts against the upper side of the upper partition plate, and the side of the upper partition plate through which the coalescing filter element passes is provided with an inward groove that abuts against the bottom of the sealing end.

[0015] By adopting the above technical solution, the lower end of the sealing end and the upper partition plate further play a sealing role, preventing water-hydrocarbon mixtures from leaking in from the side.

[0016] Preferably, a sealing cover is provided between the upper part of the sealing end and the upper surface of the upper partition plate, and an outward extension plate is provided at the upper part of the sealing end.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figure 1-4 As shown, the coalescing dehydrator includes a filter element and a baffle plate located inside the cylinder 1. The baffle plate includes an upper baffle plate 5 and a lower baffle plate 6 located at the upper and lower parts of the cylinder 1, respectively. The space between the baffle plates is a coalescing chamber 9, and the space between the lower baffle plate 6 and the bottom of the cylinder 1 is an oil outlet chamber 10. An inlet is opened on the side wall of the cylinder 1 above the upper baffle plate 5. The filter element includes a coalescing filter element 11 and a separating filter element 12. The top of the coalescing filter element 11 is connected to the cylinder 1 through a sealing structure, and the bottom of the separating filter element 12 is connected to the bottom of the cylinder 1 through an oil outlet pipe 13. The water-hydrocarbon mixture enters the upper part of the upper baffle plate 5 through the feed pipe 2, and then the water and hydrocarbons are separated by the coalescing filter element 11 and the separating filter element 12. The separated water and hydrocarbons exit from the water outlet pipe 14 and the oil outlet pipe 15, respectively.

[0035] The coalescing filter element 11 is located above the separating filter element 12 and is fastened with bolts, such as... Figure 4 As shown, the oil outlet pipe 13 is located at the bottom of the separation filter element 12, and the center lines of the three are on a straight line. The top of the coalescing filter element 11 is connected to the upper partition 5 through a sealing structure. The water-hydrocarbon mixture in the upper part of the upper partition 5 first passes through the coalescing filter element 11, and then through the separation filter element 12, separating the water to the outer surface of the filter element, while the hydrocarbons drip down through the oil outlet pipe 13.

[0036] The sealing structure includes a sealing cover plate 8 and an inlet sealing end 7. The inlet sealing end 7 is fitted on the top of the coalescing filter element 11. The inlet sealing end 7 includes an inlet end 701 and a sealing end 702. The sealing structure allows the water-hydrocarbon mixture to be stored above the upper partition plate 5 and filtered by the coalescing filter element 11 before going down, which can prevent the water-hydrocarbon mixture from directly entering the coalescing chamber.

[0037] The inlet end 701 penetrates the center of the top of the coalescing filter element 11. The sealing end 702 is integrally formed around the inlet end 701. The bottom of the sealing end 702 is an inverted U-shape with the opening facing downwards. The sealing end 702 is just stuck on the top of both sides of the coalescing filter element 11. The mixture enters the coalescing filter element 11 from the inlet end. The sealing end 702 and the coalescing filter element 11 have a sealing effect.

[0038] The lower bottom edge of the sealing end 702 abuts against the upper side of the upper partition plate 5. The upper partition plate 5 has an inward groove on the side through which the coalescing filter element 11 passes, which abuts against the bottom of the sealing end 702. The lower bottom edge of the sealing end 702 and the upper partition plate 5 further seal the seal, preventing water-hydrocarbon mixtures from leaking and flowing in from the side.

[0039] A sealing end 702 is located at the upper part of the upper partition 5 and between the upper surface of the upper partition 5 and a sealing cover plate 8. An outward extension plate 703 is provided at the upper part of the sealing end 702. The extension plate 703 is located exactly above the sealing cover plate 8 and is connected to the sealing cover plate 8 by bolts. The extension plate 703 covers the sealing cover plate 8, and the two are sealed by a sealing ring 704, which more effectively prevents water and hydrocarbon mixtures from entering the filter element from the side of the coalescing filter element 11 and ensures that they enter the filter element from the top of the coalescing filter element 11.

[0040] A sealing ring 704 is provided on the side where the sealing end 702 contacts the sealing cover plate 9. The bottom outer periphery of the sealing cover plate 8 and the upper partition plate 5 are fastened together by bolts. The bottom outer periphery of the sealing cover plate 8 is connected to the upper partition plate 5 by a sealing gasket to prevent water-hydrocarbon mixture from flowing from between the sealing cover plate 8 and the upper partition plate 5 into the side of the coalescing filter element 11 or the coalescing chamber 9.

[0041] The bottom of the oil outlet pipe 13 passes through the lower baffle 6 and is connected to the oil outlet chamber 10. The oil outlet chamber 10 is provided with an oil outlet 4 on the side. The bottom of the lower baffle 6 is provided with a water outlet pipe 3, which is connected to the coalescence chamber 9. The water outlet pipe 3 passes through the oil outlet chamber 10 and exits from the bottom of the cylinder 1. The filtered water and hydrocarbons flow out from the water outlet pipe 3 and the oil outlet 4 respectively, which can fully separate the water and hydrocarbon mixture.

[0042] The inner wall of the cylinder 1 is a smooth surface. A pipe gauge is provided on the top of the cylinder 1. A level gauge 14 connected to the cylinder 1 is provided on the side of the pipe gauge. The level gauge 14 is located near the upper partition 5 and on the side of the oil outlet pipe 14. The level value inside the cylinder 1 can be read by the level gauge 14 to determine whether to discharge water from the cylinder 1. The smooth inner wall of the cylinder 1 can prevent the liquid from accumulating on the side wall and fall directly onto the lower partition 6.

[0043] The water-hydrocarbon mixture enters the upper part of the upper baffle inside the cylinder 1 through the feed pipe 2. Then, the water-hydrocarbon mixture enters the top center of the coalescing filter element 11 through the inlet end 701. The fluid flows from the inside to the outside through the coalescing filter element 11. Tiny droplets are adsorbed on the surface of the coalescing filter element 11. The small droplets collide at the fiber intersections, coalesce and grow into large droplets, and finally fall off the surface of the coalescing filter element 11. Due to their high density, they settle on the lower baffle 6. Hydrocarbons, as organic matter, can pass through the separation filter element 12 and flow downstream through the oil outlet pipe 13 and the bottom of the cylinder 1. The large water droplets formed by coalescence are blocked by the separation filter element 12. In this way, oil and water are effectively separated. When the water accumulates to a certain height, the drain valve is manually opened to discharge the water from the coalescer.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
